Answer:

56.714°

Step-by-step explanation:

Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.

250m*sin(40°) = 250m*0.64278760968 = 160.696902422m

452.4m-160.696902422m=291.703097578m

Use pythagorean theorem:

$\sqrt{250^2 - 160.696902422^2}$

62500-25823.494448025787=36676.505552

$\sqrt{36676.505551974216}$ = 191.511110779m

arctan(291.703097578m/191.511110779m)≈56.714°

Do $8.31/3 and $12.95/5 and that will give you a price per pound and whichever is cheaper would be a better deal.

Please help me by marking the correct answer to each part of number 9. I really dont get this at all, so please tell me why your

natta225 [31]

A. False
Why? Because you cut off the triangle. The measurements are 20 mm and 10 mm.
B. True
Why? Because 20*10 = 200
C. False
Why? Because the base is 6 since 26 - 20 is 6. The height is 4, not 6 because 10 - 6 is 4.
D. True
Why? Because like question C., the base is 6, and the height is 4. 6*4 is 24/2 = 12. If you don't get this, the formula for all triangles is b*h*1/2
E. True
Why? Because from questions B. and D., the area of the rectangle is 200 and the area of the triangle is 12. 200 + 12 = 210.

Hope this helped,
